EEcircuit is a circuit simulator based on ngspice, and it runs inside the browser using WebAssembly technology. The input is schematic, and the output is the results of the analysis that you're doing in the simulations. You are able to plot and view the results directly in the browser using a high-performance WebGL plotting library webgl-plot, or download the data in CSV format for further analysis. Notice that your schematic and results are processed locally and always remain inside your browser and are never uploaded to the network. The focus of this implementation is rapid analysis and sharing circuit ideas and results within the VLSI and chip-design communities.
The next version of EEcircuit has been released! If you still require the old vesrion go to gen1.EEcircuit.com.
